 Subject                                                                        Project No.          95141.00
              Drive, Noosa Heads

This technical memorandum has been prepared by Douglas Partners Pty Ltd (DP) in response to
Council’s Decision Notice (Ref: MCU20/0128 dated 19 April 2021) and should be read in conjunction
with the previous geotechnical report entitled “Report on Geotechnical Investigation, Proposed
Youngcare Facility, 32 Viewland Drive, Noosa Heads” DP Report 95141.00 dated January 2021.

In summary the subsurface conditions encountered as part of the previous investigation comprised
sand to the termination of the bores at 3.0 m depth. The relative density of the sand was typically very
loose to loose initially, grading medium dense typically within the upper 1 m. No groundwater seepage
was encountered in the bores at the time of investigation.

The site slopes gently from the north-eastern corner at approximately RL 76.5 down at approximately
3o to the south-western corner at approximately RL 72. Inspection of the site by an experienced senior
geotechnical engineer indicates the site to be relatively flat for most parts, with no obvious or
significant scarps, hummocks, visibly disturbed ground or tension cracks which would indicate the
presence of global instability.

Reference to the Noosa Council’s Landslide Hazard Overlay, the site is not identified as being in a
landslide hazard area (refer to Figure 1).
